How do I calculate a negative exponent like 5^-3?

Enter 5 as the base and -3 as the exponent. The calculator applies the Negative Exponent Rule (a^-n = 1/a^n) and returns 0.008 (or 1/125) with the steps shown.

Can this tool solve fractional exponents such as 16^(1/2) or 8^(2/3)?

Yes. Use the fraction input mode to enter 1/2 for square roots or 2/3 for cube roots squared. For 16^(1/2), it returns 4; for 8^(2/3), it returns 4.

What is the result of any number raised to the power of zero?

Any non-zero base raised to the power of 0 equals 1 (e.g., 7^0 = 1). The calculator applies the Zero Exponent Rule automatically and flags 0^0 as undefined.

Does the calculator show the steps for the Power of a Power rule?

Absolutely. For an input like (2^3)^4, it expands the steps: multiply exponents (3 × 4 = 12) to get 2^12, then computes the final value 4,096.

How accurate are the results for very large exponents like 2^100?

The tool uses arbitrary-precision arithmetic (BigInt) to display the exact 31-digit integer result for 2^100 (1,267,650,600,228,229,401,496,703,205,376) without scientific notation rounding.

Can I use this exponent calculator offline?

Yes. After your first visit, the Progressive Web App caches all logic locally. You can calculate powers on a plane or in a basement with zero connectivity.

Is my calculation history saved or sent to a server?

Never. All processing happens client-side. We do not log inputs, results, or IP addresses. Refresh the page and the history disappears instantly.

How do I multiply exponents with the same base, e.g., 3^4 * 3^2?

Enter the expression using the multiplication operator. The solver applies the Product Rule (a^m * a^n = a^(m+n)), adds exponents (4+2=6), and outputs 3^6 = 729.
